Couple of questions

I have a second generation MacBook (black), and there are some questions bothering me.

1) I installed new 2 GB RAM. It recognizes everything okay and everything seems fine. Although everything is much faster running programs and things, it actually seems slower in booting up. Why is this? Did I screw something up?

2) My battery light blinks as it's charging. Is this normal?

3) It seems that my battery's capacity is only 69% of its original capacity. Can i fix this by recalibrating?
